Document Type and Number:
WIPO Patent Application WO/2016/175155
Kind Code:
A1
Abstract:
The present invention suppresses the occurrence of inferior bead appearance and of welding defects in horizontal fillet welding. A welding system that, using the junction at which a standing plate and a bottom plate meet as a welding line, makes an electrode weave centered on the welding line and thereby welds along the welding line. While weaving, the electrode moves forward in a welding advancement direction until a bottom-plate-side weaving edge. When the electrode arrives at the bottom-plate-side weaving edge, the electrode moves backward with respect to the welding advancement direction until a standing-plate-side weaving edge. The electrode repeats this weaving motion on the bottom-plate side and on the standing-plate side.
